Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...

Since the magnetic field is sustained by geological activity deep within our ... then another 1,400 miles of molten outer core, and finally, a dense sphere forms the solid inner core. What matters for ...

A weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...

Made of iron and nickel, the hot, solid sphere is about 70% the size of ... changes to this innermost layer could impact the planet’s magnetic field, which shields our world from solar radiation ...

But, there may be another way, albeit a rather special case, where a magnet can not only be levitated, but locked in place using a rotating magnetic field. The video shows a demonstration of how ...

In this study, researchers found that the magnetic conductivity of magnetofluid can be significantly regulated by a magnetic field ... effect between a gold sphere and a silicon dioxide substrate.

Would a dramatic change in the Earth's magnetic field affect creatures that rely on it during migration? Late on a January night in 1993 I found myself on a beach on the Pacific coast of Costa ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

Over time, changes to this innermost layer could impact the planet’s magnetic field, which shields our world from solar radiation — and helps guide the migrations of many animals. Loggerhead ...
